Part Number: IO-EXPANDER-EVM Other Parts Discussed in Thread: TCA6408A Tool/software: Hi team,
As I read from the EVM guide, only J9 & 10 should be install for the operation, however when I compare the footprint of the device, there are more different…
Hi Dheeraj,
Sorry I am not sure if I understand correctly, please correct me if any of the below is wrong. As per your observations the " AM261_OSPI0_RESET_OUT0" net is always low, as seen in the first image, the pin is always low whenever the PORz…
Hello Tushant,
To enable the I2C buffer, we need the GPIO3 pin.
You can drive the GPIO3 low to enable the I2C Buffer by default.
The GPIO4 signal you don't need to control if you make this pin low, the I2C buffer goes to reset.
Regards,
Anil.
Part Number: TCA9539 Tool/software: Dear TI Support Team,
I am contacting you regarding an ESD susceptibility issue observed with the TCA9539PWR IO Expander. During internal testing, the device fails to pass our ESD Air Discharge test at ±10KV, with…
Part Number: MSP-EXP430G2ET Other Parts Discussed in Thread: IO-EXPANDER-EVM , Hello,
I am currently trying to setup my MSP-EXP430G2ET EVM that I just recently got, with the IO-EXPANDER-EVM. I was following the instructions on how to get them to interact…
Hi Jishnu,
We do not have an IO expander that is automotive grade and supports PWM capability.
Only device currently is the TCA6507 for PWM capability.
You would have to do what Clemens was stating in earlier threads about making PWM with constant I2C…
Part Number: TCA9535 Other Parts Discussed in Thread: TCA9539 I am trying to use the IO Expander EVM board to test the aforementioned gpio expander. I do not have the MSP430 Launch Pad board that the datasheet for this EVM says is required, nor do I want…
